Wondering about the calibration of rental accelerometers? When you rent sensors from The Modal Shop, you can rest assured that they will be calibrated on a timeline that fits with your rental period and will include A2LA-accredited (in most cases), NIST-traceable calibration information. The default calibration interval is one year for most sensors, and we consider your rental period when sending out sensors. For example, if equipment is expected to be out for 5 months, the last calibration date will be within the past 7 months. 

What about the calibration frequency range? Although some sensors (for example, 393 Series seismic accelerometers) are provided with low-frequency calibrations down to 0.5 Hz, most single axis and triaxial sensor rentals include calibration from 10 Hz to upper 5% of the frequency limit of the axis. 

The Modal Shop offers a standard calibration starting at 5 Hz, but many recently purchased accelerometers may only include factory standard calibration data from 10 Hz. Notes detailing the calibration included for each sensor are available on our site. NIST-traceable low-frequency calibration is available for any standard sensor at an additional charge, and additional calibration options may be available. Contact us for details.
